180128期:塔吉克上空的月全食

塔吉克上空的月全食

如果满月突然变暗,那你看到的会是什么呢?上面这部2011年摄于塔吉克的月全食延时影像可以为你提供答案。在月全食期间,地球移动到月亮和太阳之间,导致月亮突然变暗。但月亮并不是全黑的,因为地球大气层折射了部分阳光。在这部主题影片的开头,画面看似是阳光照耀下的白天,但其实是在夜里,大地被满月的月光普照。随着月亮进入月食阶段并且变暗,风力减弱,前景中的湖面上倒映着点点星光。其中最壮观的景象是全食月周围的天空突然布满繁星,在银河映衬下更加夺目。影片最终的放大画面中,呈现出了全食月附近的老鹰星云天鹅星云三叶星云礁湖星云。在月食开始近两小时之后,月亮从地球的阴影中露出,它明亮的光芒再次照耀夜空。在本周三,将出现另一次月全食,不过,此次的主角是出现在同一个月份的第二个满月,而且是罕见的超级蓝月

A Total Lunar Eclipse Over Tajikistan

Explanation: If the full Moon suddenly faded, what would you see? The answer during the total lunar eclipse in 2011 was recorded in a dramatic time lapse video from Tajikistan. During a total lunar eclipse, the Earth moves between the Moon and the Sun, causing the moon to fade dramatically. The Moon never gets completely dark, though, since the Earth’s atmosphere refracts some light. As the featured video begins, the scene may appear to be daytime and sunlit, but actually it is a nighttime and lit by the glow of the full Moon. As the Moon becomes eclipsed and fades, the wind dies down and background stars can be seen reflected in foreground lake. Most spectacularly, the sky surrounding the eclipsed moon suddenly appears to be full of stars and highlighted by the busy plane of our Milky Way Galaxy. The sequence repeats with a closer view, and the final image shows the placement of the eclipsed Moon near the Eagle, Swan, Trifid, and Lagoon nebulas. Nearly two hours after the eclipse started, the moon emerges from the Earth’s shadow and its bright full glare again dominates the sky. This Wednesday another total lunar eclipsewill take place — but this one will be during a rareSuper Blue Blood Moon.
